IMPROVEMENT IN ADJUSTABLE SHARES FOR CORN -PLOWS.

Specification forming part of Letters Patent No. 7,315, dated April 23,1850.

To all whom it may concern:

Be it known that I, DAVID WOLF, of North Lebanon Township, in the countyof Lebanon and State of Pennsylvania, have invented certain new anduseful Improvements in Corn Shovel-Cultivators, of which the followingis a full description, reference being to the drawings hereunto annexed,and making part of this specification.

Figure 1 represents a perspective birds-eye view of the frame, scrapers,&c. Fig. 2 is a view of the rear side of one of the scrapers, showingits attachment to the beams of the frame. Fig.3 is a rear-elevation ofthe scraper detached. Fig. 4 is'a sectional view, showing the wedge forregulating the angle of the tongue, and thereby the depth ofcultivation.

The same letters refer to the same parts on the above figures.

A A are the twooutside beams of the frame, whose forward ends aresecured to the tongue by a bolt, B. U G are two additional beams,arranged insideot' the beams A A. D D are the handles. The beams AandGare connected and braced by transverse timbers E E in the form ot'atriangle. Fjs the tongue; G, the whiffletree.

H is a carryingbar, which is affixed to the end of the tongue by meansof a screw-bolt, H, and ring, so that the bar may be placed aboveorbeneath the tongue, as required to run the scrapers deeper or shallower.The carryiug-barH is attached to the hames of the horses, so that byplacing it above or beneath the tongue will increase or diminish thedepth of the scrapers in the earth; or the end of the tongue may beraised or lowered by means of a wedge, N and staple 0, attached to theunderside ot'the cross-beam E, through which also passes the inner endof the tongue to accomplish the same object, as represented in Fig. 4,the bolt B serving as the fulcrum of said tongue.

My improvements relate more especiallyto the manner of attaching thescrapers or shovels to the beams, so that they may be;regulated nearerto or farther from each other, to suit the character of the culturerequired, and also by which they can be adapted for furrowing the landfor the purpose of planting.

I I are the scrapers or shovels, made and shaped in the form representedin the drawings Figs. 2 and 3. These scrapers are secured to the shanksJ J by means of screwbolts K K K, said shanks being attached to thebeams A and O by confining-boltsL L, which are passed through openingsaa in the beams. The shanks J J are made large at their upper ends toform supports for the beams, and openings into which the confiningboltsL L are screwed. V

M Mare brace-rods, secured to the shanks and scrapers by the screw-boltsK K and to the beams A G by screw bolts N N, which brace and 'hold thescrapers securely to the frame. The holes a a in the beams A O are forthe purpose of receiving the confining screw-bolts, and are about fourinches apart in the beams A and two inches in the beams O, by whichtheir inner ends are set nearer to or farther from each other, withoutmoving their outer ends, by loosening the screws K K of theshanks J andplacing the screw K of the shank J in one of the holes, 0, in thescraper nearer to or farther from their outer ends, and atthe same timewithdrawing the bolts L from the inner beams, G, and moving the innerends of the scrapers to or from each other until the opening in the headof the shanks J is coincident with one of the holes, a, in the beam 0,when it is secured as before. The scrapers may also be moved entirelyfrom each other, to increase the space between them and set moreobliquely to each other, by withdrawing the bolts L L and placing themin other openings in the beam, by which they can be adapted forfurrowing the earth for the purpose of planting corn, thusdispensingwith the labor of furrowing the field with the plow in the usual mannerafter it has been plowed and harrowed, ready for the reception of thegrain. This feature combined with the cultivator is deemed important.and useful.

The operation of this cultivator is somewhat analogous to others. inuse, the scrapers or shovels being made to run on either side of the rowof corn, plowing down the grass, and scraping and billing the earth moreor less aroundthe corn, according to its growth, the implement beingadaptable to wide or narrow planting, at pleasure, as aforesaid.

Having described my improvements in the corn shovel-cultivator, I wishit to be understood that I donot claim any of the parts thereofseparately considered; but

What- I do claim as my invention, and desireto secui e by Letters Patentis- Increasing or diminishing the angle of the plows with the centralline of draft by shifting the screws K K to the holes 0 in the plows andthe screws L L to the other holes in the beams O 0 without changing theposition of the shanks J J, and braces M M, by which more or less earthmay be thrown toward the row of plants under culture, as described. Intestimony whereof I have hereunto signed my name before two subscribingwitnesses.

DAVID WOLF.
